Abstract: A guide rail device for laterally guiding a rolling door or rolling grille armor of a rolling door or rolling grille includes a guide rail for vertically guiding the rolling door or rolling grille armor, an infeed funnel for guiding the rolling door or rolling grille armor into an entry area of the guide rail, with the infeed funnel being movable relative to the guide rail, and a damping body connected to the infeed funnel which dampens vibrations and shocks of the infeed funnel. Further, a rolling door or rolling grille includes a first guide rail device and a second guide rail device. In particular, the guide rail of the first guide rail device is fixed laterally on the building opening, and the guide rail of the second guide rail device is fixed laterally on the opposite side of the building opening.

Abstract: A rolling shutter comprises a winding shaft having a rolling shutter curtain formed from metallic premade rolling shutter curtain bars. The rolling shutter curtain is configured to be wound up on the winding shaft into a winding bale, and comprises a set of damping bodies. The damping bodies are formed from a synthetic foam material, an elastomer material, and/or a textile material. The damping bodies can be detachably mounted to the rolling shutter curtain bars.

Abstract: A roller shutter curtain sectional slat is provided with thermal insulation between an inside and an outside. For this purpose, the sectional slat preferably has two panel elements only connected with each other by an intermediate element of poorer thermal conductance than the material of the panel elements. Hinge profile areas are only present on one of the two panel elements. Moreover, a roller shutter curtain is made of such sectional slats and a roller shutter equipped therewith.
